( Figs 11, 12 View FIGURES 11–18 , 165 View FIGURES 164–166 , 238 View FIGURES 234–239 )

Bizone Bianca Walker, 1856   , List of the Specimens of Lepidopterous Insects in the Collection of the British Museum 7: 1684 (Type locality: “Hindostan”).

Type material examined. Holotype (by monotypy) ( Figs 11 View FIGURES 11–18 , 165 View FIGURES 164–166 ): male, “Hind[ostan]” / “ Bizone bianca   type Walk.” / “ Bianca n.” / “Type” / “226” / “501” / “A. Walker’s type of Bizone bianca   7-1684” / “TYPE (printed) LEP.: No. 429 Bizone bianca Walker   (handwritten) HOPE DEPT. OXFORD (printed)” (Coll. OUMNH).

Other material examined. MEGHALAYA: 1 ♂, India, Meghalaya , Dangar, 30.VIII.2014, leg. H.S. Datta (Coll. NZCZSI)   ; 2 ♀, NE India, W Meghalaya, Umran , 33 km N Shillong, 26°06’N, 92°23’E, 800 m, 14–23.VII.1997, leg. Sinjaev & Afonin, slide ZSM Arct. 2019 GoogleMaps   - 332 ♀ Volynkin (Coll. MWM / ZSM)   .

Diagnosis. Forewing length is 13–14 mm in males and 18–18.5 mm in females. Cyana bianca   is most similar externally to C. juliettae   (illustrated by Volynkin & Černý (2019b): fig. 2) and C. carmina   ( Figs 13, 14 View FIGURES 11–18 ), but can be distinguished by the black outer margin of its antemedial line being arcuate, while in C. juliettae   and C. carmina   that is curved outwards at the anal wing margin. In addition, in C. bianca   this margin is stronger curved at costa than that of C. carmina   . In the male genital capsule, the valva apex is slightly broader than that of C. juliettae   (illustrated by Volynkin & Černý (2019b): fig. 14) and C. carmina   ( Figs 166 View FIGURES 164–166 , 167 View FIGURES 167–169 ). The vesica shape of C. bianca   is most similar to that of C. carmina   , but differs by its smaller dorsal medial diverticulum, narrower dorsal distal diverticulum covered with weaker spinules and granulation, larger apical diverticulum, smaller lateral diverticulum bearing narrower cluster of smaller spinules, and less granulated ventral distal diverticulum bearing smaller patch of spinules. The female genitalia of C. bianca   are similar to those of C. carmina   ( Figs 239 View FIGURES 234–239 , 240 View FIGURES 240–245 ), but differ by the longer apophyses anteriores and longer sclerotized anterior section of ductus bursae.

Distribution. India (Meghalaya) ( Walker 1856; Volynkin & Černý 2019b).
